I hate american christian fundamentalist like any sane person, but you have to admit that the fetus is not entirely part of woman’s body - it’s on its way to become its own “thing”… And the longer it grows, more “own” it is. With different DNA etc. While I vehemently refuse anyone dictating these kind of things to anyone else - thaťs just forcing their will upon someone, in one of the most important questions - I found this “my body” view the weakest part of the defense.
